PLANT-STAND.

Specification of Letters Patent.

Patented May a, 1915.

Application filed March 27, 1914. Serial No. 827,695.

To all whom it may concern:

Be it known that I, CHARLES T. BOONE, a citizen of the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Plant-Stands; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, ref erence being had to the accompanying drawings, forming apart of this specification.

The objects of my invention are: First, a stand for supporting plants or other movable objects, which may be extended to ac commodate an increased number thereof; second, a knock-clown, portable stand for plants, the parts of which are adapted to be detached and arranged within a small compass; third, a hoist for extensible frames in plant stands; and fourth, bases for extension plant stands, in which the floor is inv sectional interchangeable parts.

The invention consists in the novel con struction and combination of parts, such as will be first fully described and then specifically pointed out in the claims.

In the drawings: Figure 1. is an isometric front view of the novel plant stand, in

readiness for use and prior to being extended. Fig. 2. is a view of the stand, similar to that seen in Fig. 1, and showing the parts extended in position. Fig. 3. is a vertical, sectional view of the stand, as seen extended in position in Fig. 2, and takenupon the line as, w, in Fig. 4Q Fig. 4. is a plan view, in detail, of the extensible base frame, and the hollow post or standard, with the top or cap plate removed, showing in, dotted lines, the extended position of the frame.- Fig. 5. is a view, in perspective, of thebase frame, and the hollow post, taken from a position in rear of the post, showing the recess for the hoisting ropes, and the hinged door closing the recess in an open position, the

frame being shown in a closed position.v

Fig. 6. is a detail view, in perspective, of

the detachable hub plates supporting the porting the adjustable shelf-supporting frame.

Fig. 8. is a detail view, in per-.

spective, of one of the extension bars of p the shelf-supporting frame, broken away at one of the ends. Fig. 9. is a detail rear view of the hollow post, carrying the rack, as seen, in Fig. 5, with the door removed showing the hoisting ropes connected with the rack bar, the outer vertical plate being broken away, to show the openings in the plate, for the passage of the rack-bar op porting frame 14, and hoisting mechanism.

15, for the former frame 12, operable in the extension of the latter frame 15. The base frame 12 consists of a hub section 16, composed of an upper semi-circular member or plate 17, and a low semi-circular plate or member 18, of the same dimensions, which are spaced apart horizontally, one above the other, the plate 18 being movably supported upon the casters 19, secured to the lower surface thereof. In the rear, straight surfaces of the hub plates 17 and 18, are wide notches 20, of equal depth, for the purp'osefurther explained. Between the plates 17 and 18,

of the hub member 16, are extended theinner ends of the radial supporting bars 21, which as seen in Figs. 4, 5 and 6 are four in number, the said ends being spaced apart at equal distances from each other, and arranged in position a short distance inwardly from the curved line of the inner portions of the plates 17 and 18, and are secured pivotally in position by means of the bolts 22, whichextend in a vertical direction through both plates 17 and 18 and the inner ends of the bars 21, said bolts having their heads 23 fiush with the upper surface of the plate 17, the lower ends of the bolts being screwthreaded at 24, and provided with the nuts 25, which bear against the lower surface of the plate 18.

The outer end portions of the bars 21 ex- 7 boxes from each other.

faces of the two lnnermost extension boxes tend outwardly a considerable distance, and are fitted within the open ends of the extension boxes 26, which are as shown, each of which consists of longitudinal side plates 27, of the requisite length, and of the proper distance apart to permit of the free telescopic movement of the bars 21 between them, and a bottom plate 28, and an outer end plate 29. In the side plates 27, of the boxes 26, are longitudinal openings 30, and in the bars 21 are secured the guide pins 31, which extend through said openings 30, and serve to retain the said bars in their proper positions within the boxes 26. To the lower surfaces and outer and inner ends of the bottom plates 28, of the extension boxes 26, are secured the blocks 32*, and the casters 32.

Brace bars 33, pivoted together at 34, are secured at 35 pivotally to the outer end portions and lower surfaces of the bottomplates 28, of the adj acentoutermost extension boxes 26, and serve to limit the movement of said To the inner sur- 26 are connected rigidly the inner ends of the adjusting bars 36 and 37. Upon thebar 36 is fixed a loop 38, in which the outer end of the bar 37is adapted to slide.

Upon the upper surface of the hub plate 17, and secured thereto by the screws 17 is mounted the lower end of a hollow post 40, which as shown is square in cross section, the box being formed to coverthe'central portion of the upper surface of said plate 17. The inner surfaces of the side plates 41, of the box 40, are placed in a vertical plane with the parallel sides ofthe notch 20, and the inner portions of said plates extend inwardly to the line of the curved surface of plate 17. Between the inner surfaces of plates 41, is secured the inner vertical box plate 42. The outer, vertical plate 43, of

V the box 40, is arranged a short distance inwardly from the lines of the vertical outer surfaces of the'sides 41, so as to provide a recess 44, betweenthe outer surface of plate 43 and the adj acentsurfaces of the plates 41. This recess 44 is covered by a door 45, composed, as seen, of an outwardly-curved plate,

v oted a gear wheel 50, the teeth of which exhinged at 45 to the outer surface of one side plate 41. Between the inner surfaces of the side plates 41 andithe'inner and outer end plates 42 and 43, respectively, is formed a vertical opening 46, within which is fittedv to move easily a sliding bar 47, of the requisite length, upon the surface of which bar, in the direction of the inner surface of plate 43, is a toothed rack 48, extending the length of the bar, the teeth being narrow in width. In the plate 43, at a point a short'distance downwardly from the line of the upper end of post40, 1s an opening 49, ,in which is pivtendto and mesh in the teeth of the rack 48.

The purpose of thegear wheel is to guide below the gear wheel clear for the entry'of the hoisting ropes. This rack 47 forms a part of the hoisting mechanism for the shelfsupporting frame 16, which consists of' a cap plate or shelf 51, which as shown is semi-circular in form, to the lower surface of which is secured rigidly a flat plate 52, of the same form as the plate 51, but smaller in size. The plates 51 and 52'are secured rigidly to the upper end of the rack bar 47, in any'convenient manner, a screw '53 being shown for that purpose. I

The shelf-supporting frame 14 consists of the upper bars 54, which as shown are three in number. Tothe lower surface and upper ends of each bar is connected one leaf of a strap hinge 55 (see Fig. 7 ),'the other leaf being pivotally connected at 56, with the lower surface of the plate 52, on the rack bar 47. One of the hinges is secured to the plate upon a line transverse to the longitudinal axis of the bar 47, the other hinges being secured at equal distances therefrom and upon a line concentric with the curved surface of the plate 52. 7

The longitudinal surface of the bars 54 are beveled at 54 (see Fig. 8).. The lower portions of the shelf-supporting frame consists of extension members or boxes 56, which are provided with longitudinal grooves 57, extending through their upper surfaces and upper ends of the bars. The rear and inner surface of the grooves 57 permits the attachment of shelf supports when the bars 54 are extended as further described. The lateralsurfaces of the grooves 57 are provided with V-shaped grooves 58, within which grooves are extended telescopically the outer end portions of the bars 54, which are of the proper length'for extension within the boxes 56. The lower ends of the extension boxes '56 are cut away at 59, upon a line horizontal with the upper surfaces of the extension boxes 26, of the base frame.

The hoisting devices for the rack bar 47 consist of the separate hoisting ropes 60, 61 and 62. The inner ends of these ropes are inserted within the respective openings 60 61 62*, in the lower end of the rack bar 47, and made fast to said endv (see Fig. 9). From thence, the outer ends of said ropes pass upwardly between the inner surface of the rack bar and the vertical plate 43, of post 40. The outer end of the rope 60 passes in line with therack teeth 48, through an opening 63, in the plate 43, a short distance below the opening 49, for the rack bar guiding gear wheel 50, in which opening 63 is a guide roller 64. Fromthence, said rope extends downwardly within th'e'recess 44,.in the post 40, thence past the notches 20, thence over a guide roller 65, secured to the lower surface of the hub plate 18, thence extended outwardly and secured to a pin 66, on the lower surface of the adjusting bar 36, for the innermost extension boxes or members 26, of the base frame (see Fig. 3). The outer ends of the ropes 61 and 62 extend upwardly on opposite sides of the rack 48, thence through separate openings 67 and 68, in the plate 43, which are located a short distance below the position of the opening 63, thence I over the guide rollers 69, in said openings.

From said rollers, the said ropes extend downwardly within the recess 44, thence over guide rollers 7 O, on the lower surface of the hub plate 17 within the notch 20, thence extended forwardly and connected with the pins 71, on the inner end portions of the two adjacent inner extension boxes 26, of the base frame. The floor for the base frame is composed of separate segment boards, and with the exception of the two outer ones, removable when the parts of the stand are extended.

As seen in Fig. 1, the outer segment boards 72 and 7'3are fixedly connected by screws 73, with the upper surfaces of the respective outer extension boxes 26, of the base frame. The inner end of the segment boards are curved inwardly at 7 2*, and 73*, and fit snugly against the curved surface of the hub plate 17, upon the upper surface of which plate are secured the inner ends of the outwardly-extended guide plates 74. The removable members or boards of the floor consist of the triangular shaped boards 75 and 76, which are adjacentthe inner surfaces of the respective fixed boards 72 and 73, and terminate at a point, these boards being provided with dowel pins 77, which enter openings therefor in the boards 72 and 73. The next floormembers 78 and 79, which are adjacent the respective boards 75 and 76, are increased in width, and also abut at their inner, curved ends, with the hub plate 17. Between these boards 78 and 79 is the intermediate board 80, of increased width to that of either board 78 or 79, these boards 78, 7 9 and 80, havin dowel pins on their radial surfaces, and oined together, as described of boards 72 and 75.

Upon the lower ends of the extension boxes 56, of the shelf frame, which are extended toward the respective boards 72 and 7 3, are connected the hinges 81, one leaf of each of the hinges being secured to the said end of the boxes, and the other leaf secured to the upper surfaces and outer end portions of the fixed boards 72 and 73, respectively.

Upon the lower end portion and side of the intermediate extension box 56 is secured a bolt 82, the outer end of the bolt extending within a bolt opening 83, in the outer end portion of the board 80. The shelf supports are mainly supported by the bars 54, and, as seen, are formed from short lengths of wire, bent at right angles, to form the horizontal rests 85, and risers 86, the latter being long or short, in proportion to the number of shelf rests required. As arranged, the inner ends of the upper shelf rests are secured within openings in the bars 54, at a point a considerable distance downwardly from the upper ends of said bars, and the risers for the lower shelf support secured within the openings 86*, these supports being in series, and the risers on each bar 54 being the same in height.

Upon the horizontal shelf supports 85 are laid the shelves 88. These shelves are formed in the arcs of circles, and vary in length, the lower shelf obviously being the greatest in length. The shelves are formed in two sections 89 and 90, separated transversely, at a point intermediate the ends of the shelves, and said parts connected together by hinges 91 (see Fig. 10), and over the joints extend the joint-closing plates 91*.

The plant stand constructed as heretofore described, and as seen in Fig. 1, may now be employed for the uses designed, the floor afiording as large an area for the plants as the shelves, and furthermore, the closeness of the joints of the floor-sections prevent the loose soil from being scattered, and upon which plants may be exchanged and moistened.

l Vhsn an increase in the size of the stand is desired, the floor members 75, 76, 78, 79 and 80 are removed from each other and the base frame, the bolt 82, on the extension box 56, being first removed from the opening 83, in the floor member 80. Suflicient power is now applied to the extension boxes 26, of the base frame, and said boxes drawn outwardly to their full extent, at the same time drawing upon the ropes 60, 61 and 62, and hoisting the rack bar 47, which, in moving upwardly with the. cap plates 51 and 52, draw upon the bars 54, and drawing said bars from the extension boxes 56 the full height required. In place of the intermediate floor member 80, I now employ (as seen in Fig. 2) a like floor member 92, which is of increased length to that of the floor member 80, upon the lower surface of which is a block 93, which block, when the rack is in an elevated position as seen in Figs. 2 and 3, comes into contact with the inner, adjusting bar 36, and locks the parts in their outwardly-extended positions. It will now be seen that space in the groove 57 in the extension box 56, below the lower ends of the bars 54, afford space for the attachment of another shelf support 94, independent of the shelf support 85, as seen at 94, affording supports for an additional shelf 95. The extensions of the bars 54 also afiord means for adding thereto, at their upper ends, like shelf supports, and thereby add to the efliciency and plant-supporting capacity of the plant stand. In place of the fioor members 75, 76, as in Fig. 1, the floor members 96 and 97, as seen in Fig. 2, are employed, the inner ends of which board are provided with outwardly-curved extensions 98, which fit against the curved hubplate 17, beneath the retainingbars 74, and in the space formed by the Outward movement of the floor members 72 and 73, which move outwardly with the extension boxes 26, of the base frame.

In place of the floor members 78 and 79, in Fig. 1, floor members 99 and 100, of increased lengths, are employed, as seen in Fig. 2, the increase in length of these substituted members being also accompanied with an increase in width, in proportion to the extension of the parts of the stand, as before described.

It is obvious that the invention is applicable to a stand in which the base frame may form a complete circle, if desired, the purpose being to not only afford means for increas ing the'supporting capacity of the stand, but to make a portable stand, the parts ofwhich may be separated and quickly put together, and accommodate itself to the space allowed for display purposes.

The invention is adapted to the display of goods in store windows, and other uses, such as fruit drying, in which the stand may be given any extended heightrequisite'for-the purpose.

Such modifications of the invention may be employed as are within the scope of the appended claims.
